Bart's solution fails for that case, too, btw:

% cd $(mktemp -d)
% HOME=$PWD ZDOTDIR=$PWD exec zsh -f
% print 'exec true' >| .zshrc
% exec zsh -d &
[1] 81931
%
[1]  + suspended (tty output)  exec zsh -d
% exec fg
[1]  + continued  exec zsh -d
zsh: can't set tty pgrp: interrupt

[Process completed]
